Due tothe'force of the v relatively heavy sprin 'l referabl employ toactuallyactue P Y provide a quick acting and sure stop motion mechanismfor the machine if anything, quicker thanany type of electric stopmotionmechanisms.

A further obj ect of my invention is to provide stop motion mechanism ofthis type.

Which may be readily connected to a braiding machine Without in anyrespect modifying the constructionthereof. I merely insert the beam forthe elastic-cores having the necessary parts of mystop motion mechanismat tached thereto underneath the braiding'machine'and attach a rodtherefrom to the usual stop motion mechanism of'the braiding machine. Vc

A further object of my invention is to provide a trigger actuatedlatch'for thisor any purpose WhlCl'l'lS releasable on .a relativelylight force to permit a relatively heavier force to act and particularlyWhere a large fo ceisr q r te l sws or iQn l e c I carrier 1s PTOVIdGd'W1 anism or for any other desired purpose.

so braider car riers18 revolve-asusual in the sinuous cr0ssc tracksn'the top plate 20 and are driven as usualby the gearing 22 su tablyrevolved by the pulley 24 Between; the gearing 22 pulley i thereisinterposedthe usual clutch 26. I

The frame 12 is provided with thesuitable holes 27through whichtheelastic cores 28 may them the usual cord. 1

be led tohav e braided around While my elastic core stop motionmechanism may actuate any desired type of stop it to motion mechanism Ipreferably soconnect' v the braiding .machine that'it may act uponthealready existing type of stop motion mechanism already built on mosttypes of braiding machines to stop the machine 'When a thread or acid inone of the braider' reason, each braider carries breaks for any eight soslidwe" ably mounted on a post 32 thereof normally held up by the cordduring the braiding op III oration and adapted toslide down the post 32to move over the pivoted lever 34 to actuate the stop motionmechanism asthe lowered weight comes adjacent to the lever 34 as thecarrierwindsaround the sinuous with the functioning of crossing tracksafter breaking of the cord.

36 represents the main drive shaft which has mounted thereon the drivingpulley 24 and which has on its-ginner' end the. bevel" gear 37. Saidbevel gear 37 is adapted to mesh as usual with the bevel gear 38 looselymounted on a revolvable upright shaft 40. Said upright shaft 40 haskeyed 'th'eretothe driving gear 42. lChe braiding machine is providedwith the usual clutch 26 which preferably includes comprising a clutchfork 44 adapted on the upward movement of "the shipper handle tocausethe driving gear 42' to revolve with the-continuouslv revolving vbevel gear 38. The braiding machine 13 norpivoted lever 34 to'releasethe clutch 26.

It isrthus apparent that the only modifications of a standard braidingmachine necessary are to provide the holes 27 in the frame thereof andmeans forattaching the rod to the pivoted latch 46.7 j

V The elastic cores 52 are suitably mounted as usual on the beam54in'ormalylocated un- V dern-eath the braiding machine; said beam 54 7being provided; with the usual weight brake 56. The elastic cores 52 aresuitably wound individually on different portions of the beam 54.Although my improved trigger actuated latch for the movable member maybe actuated bv a single light moving strand, as

shownin the drawings or otherwise it is pref erably so constructed as tobe actuated on the breaka e of any one of the elastic cores 52, of whichthere may be eight as shown in the drawings. l/Vhile any suitable typeof latch means may be employed on a portion of the beam stand 58underneath. the beam 54, I preferably suitably piv'otably mount the arm60, Said arm 60 has the free outer endthere- V of connected to the rod50 and an enlarged curved portion such as the disk 62 near the pivotpoint thereof having a notch 64 on'tlie upper portion of the peripherythereof. I

provide a relatively strong spring 66 con nected to the rod 50 to moveitdownwards to actuate the stop motion mechanism having the opposite endthereof suitably connected to the beam frame 58, and suitable means torelease said notch means to permit the spring to move said rod. In mypreferred embodiment I provide gravity opera-tive pivotable triggermeansoperative to release the latch means to permit, the spring 66 to movethe rod 50. The trigger means includes the pivotable trigger shaft 68normally biased against gravity by the relativelylight force of anelastic core and I- provide means such as a slidable weight 70 operativeon breakage of saidcore to increase the gravity m0- ment of said triggershaft sufficiently to release the latch means. While any suitable typeof latch means may be GITIPIOYQdfI preferably employ thepawl 72 suitablypivotably mounted on the beam frame 58 to have'an end thereof re; otedarm 60. .t V

' In my preferred embodiment, the latch gister in'the not-ch on saidpivmeans also includes the lever 74 suitably piv-' ot-ed at 7 6. to thebeam frame 58 adjacent said pawllhaving the work arm 7 8 adapted to abutthe free end 80 of the pawl 72. The power arm 82 ofsaidelever 74normally projects upwardly." ln the embodiment shown, the pivot of thelever 7 4 comprisesthe pivot rod 76 ,extending underneath the beam 54and7 parallel therewith. The trigger meansin- Ycludes a plurality ofpivotedtrigger shafts 68- one for each coresuitably pivoted as at 84 toan extension of the frame 58. Each triggeri shaft has the spool 86revolvably mountedon the normally raised end 88 of the power arm thereofadapted to receive the elastic core 52 to normally retainsaid powerarm88 in raised position; Each trigger shaft is also provided with asuitableslideway comprising the rod 90 which extends from substantiallythe pivot point 3340f said'shaft'along the 1 I also provide "a 6 powerarm 88 thereof. weight 70 having ahook 71 for mounting on said rodQOadapted in normal posit-ion, of each trigger shaft 68 during theoperation of the machine to lie. as shown in Fig.4a relatively smalldistance from the pivot point 84' thereof. As also-showndiagrammatically in Fig. 4on breakage of the core 52, the power arm 88of said trigger shaft 68 will drop and after itpasses the horizontal theweight 70 will slidevrdown the power arm of'said' shaft 68 to increasethe force of the gravity moment thereof to increase the upward force ofthe work arm 89 'ofsaid trigger shaft striking the power arm 8910f thelever 7 4 su'liicient ly to knock the pawl 72 out 'of the notch 64 topermit the spring'66 to move the rod 50 to actuate the stop motionmechanism. It is thus obvious that the latch means-will release by thedropping' of anyind-ividual trigger shaft 68 on the breakage of thecore.

In a light braiding niachi ne a single trigger actuatedlatchis'sufiicient to release the stop motion mechanism but particularly onand carrier or larger braiding machine in order to increase the forceacting on the movable member-r rod 50 stuiiciently to release the stopmotion mechanism, 1 preiierably connect two or more oi? my springactuated latches in series as shown in Fig. 5 In Fig. 5 the lever 74 isreleased as usual by the trigger'shaft on breakage of a coreto knock:the

, pawl 72 out of the notch 6% in the pivoted "no-er 9E will also bedepressed to knock the pawl arm which will permitfthe relatively lightspring 66 to movefthe rod 92. TiZherod 92 however, is not connecteddirectly to-the stop motion mechanism but a second 'sprmgac- 'tuatedlatch similar to the'spring actuated latch I normally employisinterposed lee-yt-ween' said first spring actuated latch and the stopmotion mechanism connection also suitably pivot the arm 94 to a portionof the beam frame 58and connect the free end thereof to the movable rod92. I also pivotably mount a'second pawl 96 .on said beam frame 58adapted to havethe free end thereof contacted by the pivoted 9 L- Saidpaw-196 is adapted to register in a notch 98 96 out of the notch-98inthe pivoted rotatable member 100 to permit the relatively heavier spring104 to depress the" movable rod 50a actuate with great force the: stopmotionmechanism; If it isdesired tostill further increase theirforce itis obvious that additional spring actuated latches may be connected inseries.

When the vtrigger actuated latch has func tioned to stopthe machine, itis obvious that it will be necessary :tore-set thepawl and trigger andsuitablysupport the power arm oi the trigger by a new: elastic core. Itis apparent that I have provided a very quick and sure stop motionmechanism of suffic ent strength to stop the machine and normally s heldin raised position jbythe r'elatively lightfo'r'ce only of a movingstrand;

l/Vhile I have shown my trigger actuated V latch attached to a braidingmachin it is obvious that it may be employedin any case where it may bedesired to move a member for any-purpose on breakage of a lightmovingstrand, in otherwise-.
